A closer look at one example
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.
Avoid this misunderstanding
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
